Until today I had never encountered even one read, write or checksum error on my ZFS NAS. Today I saw one checksum error coming from the mirrored SSD root boot pool which I have just installed. Unless you’re using a file system like ZFS (or NetApp / Veritas…$$$), then you’ll almost certainly never even know […]
If you should be unlucky enough to be unable to boot your OpenSolaris NAS one day, then these notes taken from a real restoration test might help you get back up and running again quickly. After setting up a supposedly robust mirrored ZFS root boot pool here using two SSD drives, I decided to give […]
When I started using this ZFS NAS for additional tasks, I realised that my boot environment was becoming more important, and was a weak point in this system. Initially I wanted to run a master copy of this website locally on this ZFS server, and that entailed installing WordPress and the OpenSolaris AMP package comprising […]
After running SXCE for the last year, due to a failed hardware upgrade, it was time to install OpenSolaris 2009.06. I was due to leave on a trip the next morning, but foolishly I decided to install a 3.5″ drive into a 5.25″ drive bay with some anti-vibe rubber grommets installed. When re-attaching the IDE […]
Matt Harrison wrote to me recently, to notify me about a guide he’d written showing how to integrate a ZFS-based OpenSolaris fileserver with Microsoft Active Directory. His guide covers all the necessary areas like: configuring Kerberos, synchronizing time/dates, enabling the CIFS server, joining the domain, user and group mapping, ZFS datasets, setting ACLs and auto-sharing […]
Recently I decided to expand the storage capacity of my ZFS home fileserver’s ZFS storage pool, which was configured to use a single RAIDZ vdev comprising of three 750 GB drives. I wanted to expand the RAIDZ vdev by adding one extra 750 GB drive. As you may or may not be aware, it is […]
An intriguing post appeared yesterday on the blog of Jeff Bonwick, where it simply shows photos of an informal meeting between Jeff and Linus Torvalds — could it be that Linux will get ZFS soon, due to changes in licensing, or could Linus be joining the ZFS team with Sun, or something else?
With the summer coming on, the ambient room temperature is increasing, and so here’s a handy script to help you monitor your drive temperatures to help prevent heat-related data loss.
Backups are critical to keeping your data protected, so let’s discover how to use ZFS snapshots to perform full and incremental backups.
I had two Gigabit ethernet ports sitting on this motherboard and I was only using one. So I decided to take the path less travelled, as you never know where it can lead…
